THREAD-GUIDE.

Specification of Letters Patent.

Patented July 119, 19211.

Application filed January 4, 1921. Serial No. 434,917.

To all whom it may concern:

Be it known that T, DAVID Arnns, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Thread- Guides, of which the following is a specification.

This invention relates to yarn guiding devices and particularly to that class of such devices in which the yarn guide proper, usuwithout loss of time and usually without re-- moving the entire device from the machine. To avoid this my invention contemplates the provision of a holder on the support, held thereon, say, by a set-screw, and removably clamping the guide proper to the holder by elastic means, as by a spring coupling engaged with the holder and having a yoke received by the eye of the guide proper. This affords a very secure and permanent means for attaching the guides proper, and it permits replacement to be readily efii'ected whenever necessary, as when the guide proper becomes broken or worn.

In the accompanying drawing,

Figure 1 shows my improved guiding de vice in place as a faller on a quilling machine, only a fragment of which is shown;

Figs. 2 and 3 are plan views, Fig. 3 showing the guide proper partly removed;

Fig. 4 is a side elevation;

Fig. 5 is a sectional view; and

Fig. 6 an elevation of the holder as seen from the right in Figs. 2, 3 and 4.

The guide proper a illustrated (hereinafter termed the guide) is one of usual type, being a porcelain piece with a. transverse eye Z) which has a lateral entrance 0 so related to. the eye as to form a crotch d at the inner end of, the eye; as usual, such guides have their inner ends so shaped as to form what becomes in the assembly of parts constituting my invention a flat base 6.

On the free end of the wire f I secure a holder g. This is a polygonal block which is penetrated axially by the wire and has a setscrew h forv securing it thereto (it not belng indispensable, however, that the holder be secured removably to the wire); from its relatively outer face extend a pair of lugs i, and in said outer face is formed, between the lugs, a transverse groove 3'. The block also has a pair of holes 70 parallel with the hole Z which the wire 7 penetrates, all three holes registering with the groove The inner face of the block forms a flat seat m.

' Then the guide occupies the relation shown in Figs. 2 and 4, to wit, with its fiat base 6 bearing square against the flat seat m of the holder, it is held in that relation by a coupling formed preferably as follows: A helical spring n abuts the back of the holder, surrounding the wire 7. There is a yoke formed of wire bent into substantially U-shape, the bend of the yoke forming a stirrup 0 and its legs having inbends 19 that at once form stops and also bring the end portions g of said legs somewhat closer together than they otherwise would be, the tips of the legs being rebent and forming hooks 1". Then assembled with the holder 9 the extremities q of the yoke legs penetrate the holes 70 of the holder and the free end of the spring 9 being engaged in the hooks r the yoke is forced back by the spring. The guide a being present, that is, by entering the stirrup through entrance 0 into crotch (Z and then turning the guide into general alinement with the end portion of wire 7, the spring acts through the yoke to hold the base e of the guide bearing square against seat m, the stops 7) being at that time sheathed in groove j. The inbendsor stops p limit the inward movement of the yoke when the guide is removed, but they are not indispensable, nor is the slot j for sheathing them. Lugs i are present to prevent accidentally unshipping the guide from the holder by merely tilting it relatively to the holder; they make it necessary first to pull the guide straight out before tilting it in order to detach the guide.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a thread guiding device, the combination of an attenuated support having an enlarged holder on one end thereof formed with a seat, a guide having a base bearing ward face of the holder.

3. In a thread guiding device, the combination of an attenuated support having an enlarged holder on one-end thereof formed with a seat, a guide having a base bearing on said seat, and a spring coupling removably holding the guide to the holder in rigid relation thereto and having a portion thereof thrustwise movable in the holder.

l. In a thread guiding device, the combination of an attenuated support havingan enlarged holder on one end thereof formed with a -seat,a guide having a base bearing on said seat, a spring bearing against a rearwardly facing surface of the holder; and a yoke holding the guide against said seat and held rearward by the spring. 7

5. In a thread guiding device, the combi e, nation of an attenuated support having an enlarged holder on one end thereof formed with a seat, a guide having a transverse guiding eye and a base bearing on the seat, and a spring coupling havinga stirrup received by the eye, said coupling holding the guide in rigid relation to the holder.

6. In a thread guiding device, the combination of an attenuated support having an enlarged holder on one end thereof formed with a seat a' guide having a transverse guiding eye and a base bearing on the seat and also having a lateral entrance to the eye, and a spring coupling having a stirrup received by the eye and adapted to be entered thereinto 'at'said entrance,'said coupling holding the guide in rigid relation to the holder. J

7. In a thread guiding device, the combination of an attenuated support having an enlarged holder 011 one end thereof formed with a seat, a guide having a transverse guiding eye and a base bearing onthe seat, a spring bearing against a rearwardly facing surface of the holder, and a substantially U-shaped yoke having its bend received by the eye of the guide and its legs extending rearwardly and engaged with the spring and being thus held by the spring pressing rearward against the guide.

In testimony whereof I aflix my signature.

DAVID AYRES.
